| Half-life | IM: ~6 days |
| Description | Pegylated L-asparagine amidohydrolase from E. coli. Pegylation substantially (by a factor of 4) extends the protein half life. |
| Indication/Disease | For treatment of acute lymphoblastic leukemia. |
| Pharmacodynamics | In a significant number of patients with acute leukemia, the malignant cells are dependent on an exogenous source of asparagine for survival. Normal cells, however, are able to synthesize asparagine and thus are affected less by the rapid depletion produced by treatment with the enzyme asparaginase. Oncaspar exploits a metabolic defect in asparagine synthesis of some malignant cells. |
| Mechanism of Action | Pegaspargase, more effective than asparaginase, converts asparagine to aspartic acid and ammonia. It facilitates production of oxaloacetate which is needed for general cellular metabolism. Some malignant cells lose the ability to produce asparagine and so the loss of exogenous sources of asparagine leads to cell death. |
| Toxicity | Adverse effects that occur more than 10% of the time include hepatotoxicity as it is known to increase serum transaminases (ALT, AST). Also known to induce hypersensitivity reactions including anaphylaxis, erythema and bronchospasm. |
| Metabolism | NA |
| Absorption | Onset of Asparagine depletion by IM is within 4 days Time to peak: IM: 3 to 4 days |
| IV: Adults (asparaginase naive): 2.4 L/m2 Distributes into CSF (reportedly reducing CSF asparagine concentrations to a similar extent as asparaginase | |
